Feature Request: Multiple points on a given axis

[ashtonchase]

Is there a way to have N number of axis points defined on an axis? See the X-axis on this diagram. It's not linear, but rather kind of segmented linear (0-2,2-50, 50-100, 100-950). The only possible path I see is to create multiple coordinates for each segment, but that then requires me to export them separately.
